9.6 CONNECTION DIAGRAMS
Audio system with one door entry call with dedicated speaker unit
Up to 3 outdoor stations can be connected without mixer. The system automatically switches to the
outdoor station from which the call was made.
If, while a door entry conversation is taking place, a call is made from one of the two temporarily excluded
speaker units, you will hear a telephone busy tone. One of the three outdoor stations can be fitted with a
nameplate for address or other information.
The speaker units of outdoor stations 1 and 2 must be configured.
At rest the open door lock command acts on the main outdoor station.
